摘要:
Generally, the present disclosure is directed to a collapsible substructure of a mobile drilling rig. In one illustrative embodiment, a drilling rig substructure is disclosed that includes a base having a fixed drill floor mounted thereon, wherein an upper surface of the fixed drill floor is positioned at an operating height above the base for performing drilling operations at a wellbore location of a drilling site. Furthermore, a raisable floor is also included that is adapted to be positioned in a lowered transportation position for transportation of the substructure to the drilling site and raised to an operating position adjacent to the fixed drill floor for performing drilling operations, wherein a height level of an upper surface of the raisable floor is lower than a height level of the upper surface of the fixed drill floor when the raisable floor is positioned in the lowered transportation position.
摘要(中):
通常,本公开涉及可移动钻机的可折叠子结构。 在一个示例性实施例中,公开了一种钻机底座结构,其包括具有安装在其上的固定钻台的基座,其中固定钻台的上表面位于基座上方的操作高度处,用于在井底位置进行钻井操作 钻井现场。 此外,还包括可升起的地板,其适于定位在运输位置较低的位置,用于将底层结构运输到钻井位置,并升高到与固定钻台相邻的操作位置,用于执行钻井操作,其中高度水平 可升降地板的上表面比可升降地板位于下降的运送位置时固定的钻台的上表面的高度低。
